Dentro da cadeia produtiva do maracujá, na etapa de produção de mudas, um fator importante que deve ser levado em consideração é o uso da matéria orgânica na composição dos substratos, devido as diversas características benéficas que o mesmo condiciona as mudas. Nesse sentido, o presente trabalho teve o objetivo avaliar a emergência e o desenvolvimento de mudas de Passiflora edulis f. flavicarpa cultivadas em substratos com diferentes fontes de matéria orgânica. O experimento foi conduzido em casa de vegetação, em delineamento de blocos casualizados, com seis repetições e seis tratamentos, contendo cinco fontes de matéria orgânica para a composição do substrato: lodo de curtume, resíduo de torrefação de café, esterco bovino curtido, resíduo de laticínio e composto urbano, além dos tratamentos sem uso de matéria orgânica (solo com e sem adubação). Foram avaliadas características de emergência e desenvolvimento das mudas, observando-se que houve maior índice de velocidade de emergência no tratamento com resíduo de torrefação de café, além de que todos os tratamentos com fontes orgânicas apresentaram respostas satisfatórias favorecendo o desenvolvimento vegetativo do maracujá-amarelo sendo recomendadas para a produção de mudas.   Palavras-chaves: Passiflora edulis f. flavicarpa, Resíduos orgânicos, Sustentabilidade   YELLOW PASSION FRUIT PLANTLETS EMERGENCY AND DEVELOPMENT IN DIFFERENT SUBSTRATES   ABSTRACT: Brazil dominates yellow passion fruit production, supplying national and international market. In the stage of seedling production  an important factor that must be taken into account is the use of organic matter in substrates composition, due to several beneficial characteristics it brings to plantlest development. The aim of this study was to evaluate the emergence and development of Passiflora edulis f. flavicarpa grown on different substrates with organic matter sources. The experiment was conducted in a greenhouse, in randomized block design, with six treatments and (tannery sludge, coffee roasting residue, tanned bovine manure, dairy and urban compost and the control - soil with and without fertilization) six replicates,. It was evaluated the emergence and emergence characteristics of the seedlings. The results showed that there was a higher rate of emergence speed in the treatment with coffee roasting residue, besides that all treatments with organic sources presented satisfactory responses favored the yellow passion fruit vegetative development being recommended for plantlets production.   Keywords: Passiflora edulis f. flavicarpa, Organic waste, Sustainability

The analysis of leaf pigments helps to understand the behavior of plant species under stress conditions. Thus, the objective of this study was to evaluate the amount of leaf pigments in SJ-02 cocoa seedlings under different irrigation depths and cultivation containers. The experiment took place at the Federal Institute of Espírito Santo, Campus Itapina, in Colatina, a city located in the northwest of the State of Espírito Santo, Brazil. A total of 144 seedlings were used, distributed in a completely randomized design, in a factorial scheme (6 × 3), where the first factor consisted of six different irrigation depths: 4; 6; 8; 10; 12 and 14 mm d-1 and the second one consisted of three different cultivation containers: polypropylene bags with dimensions of 10 × 20, 15 × 25 and 13 × 35, totalling 18 treatments, with eight repetitions. Seventy-four days after sowing, total chlorophyll content, flavonoid index and anthocyanin index were evaluated. There was no interaction between the factors studied. The 7 mm d-1 irrigation depth is the most suitable because it is practical in water management. Significance was not observed between the different cultivation containers.

Background: The chrysanthemum is one of the main flowers cultivated in the world, comprises the main merchandise of all floriculture. The difficulty in expanding the crop is related to the lack of technical information about its cultivation, mainly on the nutritional needs. Aims: Evaluate the influence of potassium doses on the development of cutting chrysanthemum plants. Place and Duration of Study: Horticulture Sector of the Federal Institute of Education, Science and Technology of Espírito Santo - Campus Itapina, between May 2017 and August 2017. Methodology: The experimental design was DIC (completely randomized design) with four treatments and twenty four replications considered useful plants within each plot. The treatments consisted of three diferent doses of potassium fertilization and one control: 0 kg.ha-1 of K2O (without any application of potassium); 60 kg.ha-1 of K2O (fertilizer used by producers in the region); 120 kg.ha-1 of K2O (recommended according to the amount of potassium in the soil analysis) and 240 kg.ha-1 of K2O (double the dose recommended by the soil analysis), being used as source potassium chloride. Results: The height of the plant presented an increasing linear, the results show that the dose of 240 kg.ha-1 of K2O was adequate in order to supply potassium in the ideal amount for the growth of chrysanthemum plants. When the diameter of the stem was evaluated, a quadratic model was generated with a maximum of 7.05 mm diameter of the stem when applied 179 kg.ha-1 of K2O. An increase in the number of leaves per plant was observed, from 27 at 0 kg.ha-1 dose of K2O to 51.75 at 240 kg.ha-1 dose of K2O. When estimating the ideal dose with the equation Ŷ = 277.7146 + 4.1805*x -0.0136*x², the dose of 153.69 kg.ha-1 of K2O provided the largest leaf area, reaching the value of 598.97 cm². The SPAD (Chlorophyll content) the linear model better explained the data with coefficient of determination (R²) of 0.79. The highest volume of fresh matter found was 81.56 grams with the dose of 203.22 kg.ha-1 of K2O. Through the adjusted model was verified that the dose that maximized the dry matter of the plant with 16.17 grams, was the dose of 161.66 kg.ha-1 of K2O. Conclusion: Doses between 150 and 240 kg.ha-1 of K2O provided positive results for the development of the plant, while doses under 150 kg.ha-1 presented unsatisfactory results.
